Introduction
Thank you for purchasing ISOtunes® LITE Professional Noise
Isolating headphones. These headphones have been specically
designed for use in noisy environments, allowing you to block out
much of the surrounding noise so that you can listen to your music or
talk on the phone without interruptions� This product has been tested
and meets the European Safety Standard EN352-2:2002 and the
ANSI standards for a hearing protector, with a Single Number Rating
(SNR) of 36 dB and a Noise Reduction Rating (NRR) of 26 dB� Full
testing details are available in the Noise Attenuation section of this

APPROVAL: ISOtunes® LITE is tested and approved in accordance
with ANSI S3.19-1974 Specications and tested to the European
Safety Standard EN 352-2:2002�
ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes® LITE
headphones are worn as directed, is closely approximated by the
dierence between the A-weighted environmental noise level and
the Noise Reduction Rating (NRR). Improper t of this device will
reduce its eectiveness in attenuating noise. Consult the enclosed
instructions for proper tting.
A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)
Example:
1� The surrounding noise level measured at the ear is 100 dB�
2� The NRR of ISOtunes® LITE is 26 dB�
3� The noise level entering the ear is approximately equal to 74dB�
Please note that the NRR is based on the attenuation of continuous
noise and may not be an accurate indicator of the protection
attainable against impulsive noise, such as gunre.

B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:
H = Hearing protection estimation for high
frequency sounds (f ≥ 2000Hz)
M = Hearing protection estimation for medium
frequency sounds (500 Hz < f < 2000Hz)
L = Hearing protection estimation for low
frequency sounds (f ≤ 500Hz)
